Sanitizers

Method	Description	Status
toString(input)	convert the input to a string.	x
toDate(input)	convert the input to a date, or null if the input is not a date.	x
toFloat(input)	convert the input to a float, or NaN if the input is not a float.	x
toInt(input [, radix])	convert the input to an integer, or NaN if the input is not an integer.	x
toBoolean(input [, strict])	convert the input to a boolean. Everything except for '0', 'false' and '' returns true. In strict mode only '1' and 'true' return true.	x
trim(input [, chars])	trim characters (whitespace by default) from both sides of the input.	x
ltrim(input [, chars])	trim characters from the left-side of the input.	x
rtrim(input [, chars])	trim characters from the right-side of the input.	x
escape(input)	replace <, >, &, ' and " with HTML entities.	x
stripLow(input [, keep_new_lines])	remove characters with a numerical value < 32 and 127, mostly control characters. If keep_new_lines is true, newline characters are preserved (\n and \r, hex 0xA and 0xD). Unicode-safe in JavaScript.	x
whitelist(input, chars)	remove characters that do not appear in the whitelist. The characters are used in a RegExp and so you will need to escape some chars, e.g. whitelist(input, '\[\]').	x
blacklist(input, chars)	remove characters that appear in the blacklist. The characters are used in a RegExp and so you will need to escape some chars, e.g. blacklist(input, '\[\]').
normalizeEmail(email [, options])	canonicalize an email address. options is an object which defaults to { lowercase: true }. With lowercase set to true, the local part of the email address is lowercased for all domains; the hostname is always lowercased and the local part of the email address is always lowercased for hosts that are known to be case-insensitive (currently only GMail). Normalization follows special rules for known providers: currently, GMail addresses have dots removed in the local part and are stripped of tags (e.g. [e-mail] becomes [e-mail]) and all @googlemail.com addresses are normalized to @gmail.com.	x
